Turning down your hot water heater can indeed save money by reducing energy consumption, as heating water accounts for a significant portion of household energy use. By adjusting the thermostat to a lower setting, you can lower your utility bills while still maintaining comfortable water temperatures.
How Does Lowering Your Water Heater Temperature Save Money?
Lowering the temperature on your hot water heater is a simple and effective way to save money on your energy bills. The U.S. Department of Energy suggests setting your water heater to 120°F (49°C) as a comfortable and safe temperature. This setting is typically sufficient for most household needs and can help reduce energy costs by 4-22% annually.
Benefits of Lowering Water Heater Temperature
- Energy Savings: Reducing the temperature decreases the amount of energy needed to heat the water.
- Extended Appliance Life: Lower temperatures can reduce wear and tear on your water heater, potentially extending its lifespan.
- Safety: A lower temperature reduces the risk of scalding, making it safer for children and the elderly.
Practical Example
Consider a family of four using a traditional electric water heater set at 140°F. By reducing the temperature to 120°F, they could save approximately $36 to $61 annually, depending on their water usage and local energy costs.
What is the Optimal Temperature for a Hot Water Heater?
The optimal temperature for a hot water heater is generally considered to be 120°F (49°C). This setting provides a balance between comfort, safety, and energy efficiency.
Why 120°F is Recommended
- Comfort: This temperature is typically warm enough for household tasks such as bathing and washing dishes.
- Safety: It minimizes the risk of scalding injuries, which can occur at higher temperatures.
- Efficiency: It reduces the energy consumption required to maintain a higher temperature, resulting in cost savings.
How to Adjust Your Water Heater Temperature
Adjusting the temperature of your water heater is a straightforward process. Here’s a step-by-step guide:
- Turn Off Power: For electric heaters, ensure the power is off at the circuit breaker. For gas heaters, set the thermostat to the lowest setting.
- Locate the Thermostat: Most water heaters have a thermostat dial near the bottom of the tank.
- Adjust the Temperature: Use a screwdriver to turn the dial to the desired setting, typically 120°F.
- Check the Temperature: After a few hours, test the water temperature at a faucet to ensure it meets your needs.
- Monitor: Regularly check the temperature to ensure it remains at the desired setting.
Potential Drawbacks of Lowering Water Heater Temperature
While lowering the temperature of your water heater has many benefits, there are potential drawbacks to consider:
- Bacterial Growth: Lower temperatures may increase the risk of bacterial growth, such as Legionella. However, maintaining a temperature of 120°F generally mitigates this risk.
- Insufficient Hot Water: Households with high hot water demands may experience a shortage if the temperature is set too low.

What is the Cost of Running a Hot Water Heater?
The cost of running a hot water heater depends on the type of heater, energy source, and local energy rates. On average, water heating can account for about 14-18% of a household’s utility bill. Lowering the temperature can significantly reduce these costs.
How Often Should You Check Your Water Heater Temperature?
It’s advisable to check your water heater temperature every six months. Regular monitoring ensures the setting remains optimal for efficiency and safety.
Can Lowering the Water Heater Temperature Affect Dishwasher Performance?
Most modern dishwashers have built-in heaters to boost water temperature. Lowering your water heater temperature should not significantly affect performance, but you may need to adjust the dishwasher’s settings if you notice a difference.
Is It Safe to Turn Off the Water Heater When Not in Use?
Turning off the water heater when not in use can save energy, especially during extended absences. However, frequent cycling on and off may reduce the appliance’s lifespan. Consider using a timer or vacation mode if available.
What Are the Signs Your Water Heater is Set Too High?
Signs include excessively hot water, high energy bills, and frequent scalding incidents. If you notice these, consider lowering the temperature to 120°F.
Conclusion
Lowering the temperature on your hot water heater is a simple yet effective way to save money and energy. By setting your thermostat to 120°F, you can enjoy reduced utility bills, enhanced safety, and a longer-lasting appliance. Regularly check and adjust the temperature to ensure it remains optimal for your household needs.
